Description

Technical Field

[0001] This application relates to the technical field of construction engineering, and in particular to a pipe-laying device for assisting construction. Background Technology

[0002] In the field of housing construction, underfloor heating is a common heating method used in most buildings. During the installation process, workers first lay a layer of insulation board on the floor, then a reflective film on the insulation board, and finally lay the underfloor heating pipes on the reflective film.

[0003] To facilitate construction, workers use pipe-laying tools to assist in laying the pipes. Existing pipe-laying tools include a bottom support and a pipe-laying bracket that rotates on the bottom support. During use, workers need to place the rolled-up underfloor heating pipe onto the pipe-laying bracket. As the pipe is pulled, the pipe-laying bracket rotates on the bottom support, thus releasing the pipe. However, throughout the construction process, workers need to continuously pull the underfloor heating pipe to pull it out. After pulling it out, workers also need to clamp the pipe with clips while laying it before securing it to the insulation board. The entire process is done manually, with low automation and low work efficiency. Summary of the Invention

[0004] To improve work efficiency, this application provides a pipe-laying device to assist in construction.

[0005] The pipe-laying device for auxiliary construction provided in this application adopts the following technical solution: A pipe-laying device for auxiliary construction includes a main frame, on which a pipe-laying rack is mounted. Two drive rollers are rotatably mounted on the main frame, forming a gap between the two drive rollers for the pipe to pass through. A drive motor connected to either drive roller is fixedly mounted on the main frame. A slide for placing clips is fixedly mounted on the main frame. An installation mechanism for installing clips on the pipe is provided on the main frame. The installation mechanism includes a separation component for separating adjacent clips, a pressing component for pressing the clips onto the pipe, and a power component for driving the separation component and the pressing component.

[0006] By adopting the above technical solution, the drive roller, driven by the drive motor, can pull out the underfloor heating pipes placed on the pipe-laying rack, thereby realizing the unwinding of the underfloor heating pipes, saving manpower, facilitating construction, and improving work efficiency. The clips on the slide rail, through the separation component, separate adjacent clips. After separation, the clips are pressed onto the underfloor heating pipe by the pressing component, thus pre-installing the clips on the pipe. Installing the clips on the underfloor heating pipes simultaneously with the unwinding process eliminates the need for manual clip installation, allowing workers to directly install the clips on the insulation board, greatly improving work efficiency.

[0007] Optionally, the slide is spiral-shaped, and the bottom of the slide forms a curved surface that flips the pin by 90 degrees.

[0008] By adopting the above technical solution, the spiral-shaped slide can accommodate more clips in a limited space, optimize the spatial layout, eliminate the need for workers to repeatedly add clips, optimize the construction process, and improve work efficiency.

[0009] Optionally, a first guide rod extending along the slide is fixedly provided on the slide, and a sliding block is slidably provided on the first guide rod.

[0010] By adopting the above technical solution, the sliding block can press on the pin located at the top of the slide. Under its own weight, the sliding block can exert a force on the pin in the slide to move along the slide, thus avoiding the situation where the pin gets stuck in the slide.

[0011] Optionally, a second guide rod is fixedly provided at the bottom end of the first guide rod, and a sealing plate is fixedly provided on the main frame. There is a nail-rowing opening between the second guide rod and the sealing plate for the nails to fall out. A top rod is slidably provided on the sealing plate, and an elastic element is provided on the sealing plate to control the movement of the top rod, so that the top rod can open and close the nail-rowing opening.

[0012] By adopting the above technical solution, the opening and closing of the nail pack opening can be controlled by the top rod, so that the nails will not fall when the nail pack opening is closed, thus avoiding the waste of nails.

[0013] Optionally, the separation assembly includes a cutting roller rotatably mounted on the main frame and a cutting blade fixedly mounted on the cutting roller. The cutting roller is located above the second guide rod, and when the pins abut against the sealing plate, the cutting blade can cut and separate adjacent pins.

[0014] By adopting the above technical solution, the rivets located on the second guide rod can be separated by the cutting blade. On the one hand, the cutting roller pressing against the rivets can press them firmly against the second guide rod, facilitating the cutting of the rivets. On the other hand, the cutting roller pressing against the rivets can also drive the rivets to move when the cutting roller rotates, making the rivets stick tightly to the sealing plate.

[0015] Optionally, the pressing assembly includes a rotating shaft rotatably mounted on the main frame, a disc fixedly mounted at both ends of the rotating shaft, and pressing claws fixedly mounted on the discs.

[0016] By adopting the above technical solution, the rotating shaft drives the disc to rotate, so that the pressing claws can press against both sides of the nail, so that the nail falls out from the nail outlet under the action of the pressing claws and is pressed onto the underfloor heating pipe, thus realizing the installation of the nail.

[0017] Optionally, the power assembly includes a first transmission gear fixedly mounted on the cutting roller, a second transmission gear fixedly mounted on the rotating shaft, a transmission belt mounted on the first and second transmission gears, and a transmission motor fixedly mounted on the main frame.

[0018] By adopting the above technical solution, the drive motor drives the rotating shaft to rotate, the rotating shaft drives the second drive gear to rotate, the second drive gear drives the first drive gear to rotate, and the first drive gear drives the cutting roller to rotate, thereby realizing the synchronous rotation between the rotating shaft and the cutting roller.

[0019] Optionally, the elastic element is a first spring, one end of which is fixed to the sealing plate and the other end is fixed to the push rod. A cam is fixedly provided on the rotating shaft, and a groove is provided on the cam. When the push rod extends into the groove, the nail hole opens, and when the push rod abuts against the cam, the nail hole closes.

[0020] By adopting the above technical solution, the push rod is always pressed against the cam under the action of the first spring. When the cam rotates, the push rod slides on the sealing plate, thereby realizing the control of the opening and closing of the nail hole.

[0021] Optionally, the pipe placement frame includes a base rotatably mounted on the main frame, a first support plate fixedly mounted on one side of the base, and a second support plate hinged to the other side of the base. A support rod is fixedly mounted on the first support plate, a pressure rod is slidably mounted on the second support plate, and a second spring is provided on the second support plate for pushing the pressure rod to move closer to the support rod.

[0022] By adopting the above technical solution, when placing the underfloor heating pipe, the second support plate is rotated to a horizontal position, making it easier to fit the underfloor heating pipe onto the support rod. After placement, the second support plate is rotated to a position parallel to the first support plate, and the pressure rod can press against the underfloor heating pipe under the action of the second spring, making it less likely for the underfloor heating pipe to loosen during unwinding.

[0023] Optionally, a limiting groove is provided on the first support plate, and a limiting block is fixedly provided on the pressure rod. When the limiting block is located in the limiting groove, the support rod and the pressure rod are parallel to each other.

[0024] By adopting the above technical solution, when the second support plate is rotated to the point where the support rod and the pressure rod are parallel to each other, the limiting block is moved into the limiting groove, which guides the movement of the pressure rod and fixes the second support plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By rotating two drive rollers to move the underfloor heating pipes, the pipes can be unwound, saving manpower from pulling them and making the work easier and more efficient for the workers.

[0026] 2. Adjacent clips are separated by a separating component, and then the pressing component installs the clips onto the underfloor heating pipes, achieving automatic installation of the clips and eliminating the need for manual installation, thereby improving work efficiency.

[0035] To provide a clear explanation, we will first explain the type of card used in this application.

[0036] Figure 1 These are the clips used in existing technology, as described below. Figure 1 The existing clip structure is described.

[0037] The clip includes a U-shaped connecting part and sharp points integrally formed at both ends of the connecting part. In use, the connecting part is fitted onto the underfloor heating pipe, and the sharp points are driven into the insulation board to secure the pipe. The clips used in this application are underfloor heating row clips, with a structure consisting of multiple independent clips aligned and arranged in a row. An integrally formed connecting band at the top of the connecting part secures the multiple clips together, ensuring the row clips maintain their row-like structure.

[0038] The technical solutions in this application will be further described in detail below with reference to the accompanying drawings.

[0039] This application discloses a pipe-laying device to assist in construction. Please refer to... Figure 2 A pipe-laying device for construction assistance includes a main frame 1. A handle is fixedly installed on the top surface of the main frame 1, and casters with brakes are installed on the bottom surface of the main frame 1 to facilitate the movement and parking of the main frame 1 by workers.

[0040] Please refer to Figure 2 and Figure 3The main frame 1 is equipped with a pipe-laying rack 2 for holding rolled-up underfloor heating pipes. The pipe-laying rack 2 includes a base 21 rotatably mounted on the main frame 1, with a through hole for the underfloor heating pipe to pass through, located at the center of rotation of the base 21. Because workers need to continuously bend the underfloor heating pipes at different angles during installation, the pipes may become twisted. If this twisting is not addressed, it will affect the bending of the pipes and hinder installation. In this case, the twisting can be released by rotating the pipe-laying rack 2, allowing the pipes to relax and facilitating installation.

[0041] Please refer to Figure 2 and Figure 3 The pipe-laying frame 2 also includes a first support plate 22 fixedly mounted on one side of the base 21 and a second support plate 23 hinged to the other side of the base 21. A support rod 221 is fixedly mounted on the first support plate 22, and a sleeve 24 is rotatably mounted on the support rod 221. In use, the rolled-up underfloor heating pipe is placed on the sleeve 24. When the underfloor heating pipe is unwound, the sleeve 24 rotates on the support rod 221, thereby reducing the resistance when unwinding the underfloor heating pipe. The second support plate 23 is slidably connected to a pressure rod 231 via a connecting rod 233, and the sleeve 24 is also rotatably mounted on the pressure rod 231. The connecting rod 233 is fixedly connected to the second support plate 23 and passes through the pressure rod 231, allowing the pressure rod 231 to slide on the connecting rod 233. A second spring 232 is fitted onto the connecting rod 233. One end of the second spring 232 is fixed to the connecting rod 233, and the other end is fixedly connected to the pressure rod 231. The second spring 232 pushes the pressure rod 231 to move closer to the support rod 221. When the second support plate 23 is rotated to a state parallel to the first support plate 22, the sleeve 24 on the pressure rod 231 can press against the underfloor heating pipe on the support rod 221, thus preventing the underfloor heating pipe from becoming loose.

[0042] Please refer to Figure 2 and Figure 3 A limiting groove 222 is formed on the first support plate 22. The limiting groove 222 is a dovetail groove with an open end. A limiting block 2311 matching the limiting groove 222 is fixedly provided at the end of the pressure rod 231 away from the second support plate 23. When the second support plate 23 is rotated to a state parallel to the first support plate 22, the pressure rod 231 and the support rod 221 are parallel to each other. At this time, the pressure rod 231 is lifted, so that the limiting block 2311 can slide into the open end of the limiting groove 222. This not only guides and limits the up and down movement of the pressure rod 231, but also keeps the second support plate 23 in a vertical state, thus fixing the second support plate 23.

[0043] Please refer to Figure 4Two drive rollers 31, made of rubber, are rotatably mounted on the bottom surface of the main frame 1. A gap, slightly smaller than the diameter of the underfloor heating pipe, is formed between the two drive rollers 31 to allow the pipe to pass through, ensuring the drive rollers 31 can better press against the pipe. Simultaneously, anti-slip textures are formed on the circumferential surface of the drive rollers 31 to prevent relative slippage between the pipe and the rollers. A drive motor 32 is fixedly mounted on the main frame 1, and its output is connected to either drive roller 31, causing it to rotate. The rotation of the drive roller 31 under the action of the drive motor 32 pulls the underfloor heating pipe out of the unwinding rack 2, thus unwinding the pipe.

[0044] Please refer to Figure 4 Multiple support rollers 11 are rotatably mounted on the bottom surface of the main frame 1. These support rollers 11 are arranged along the direction of movement of the underfloor heating pipes and support them below the pipes. The circumferential surface of each support roller 11 has an arc-shaped groove that matches the underfloor heating pipe, preventing the pipe from easily falling off as it moves along the roller. It should be understood that to improve the stability of the underfloor heating pipes as they move below the main frame 1, the number of support rollers 11 can be further increased. Support rollers 11 can also be mounted above the underfloor heating pipes, pressing them down. In practical applications, the number of support rollers 11 can be increased or decreased as needed; no restrictions are placed here.

[0045] Please refer to Figure 3 and Figure 5 A spiral-shaped slide 4 is fixedly installed on the main frame 1 to hold clips, allowing for more clips to be accommodated in a limited space and avoiding the need for workers to constantly add clips, thus improving work efficiency. The curvature of the slide 4 also prevents excessive bending of the clips as they move along it, ensuring smooth movement. When clips are placed in the slide 4, they are in a folded position, with the open end facing the side wall of the slide 4. This placement allows the connecting strip on the clip to bend normally, facilitating movement along the spiral slide 4. If clips are placed upright in the slide 4, the connecting strip may tear as they move along the slide 4, causing some clips to fall off and affecting their movement.

[0046] Please refer to Figure 3 and Figure 5A first guide rod 41 is fixedly installed on the slide rail 4. When a pin is placed in the slide rail 4, it is simultaneously fitted onto the first guide rod 41, allowing the first guide rod 41 to guide the movement of the pin. The first guide rod 41 extends along the slide rail 4 in a spiral shape, and a sliding block 42 is slidably fitted onto the first guide rod 41. The sliding block 42 can abut against the pin, thereby pushing the pin to move along the first guide rod 41. A notch is provided on the sliding block 42, through which the first guide rod 41 passes. The notch allows the sliding block 42 to slide along the first guide rod 41 and also facilitates the removal of the sliding block 42 from the first guide rod 41, thus allowing the pin to be added to the slide rail 4. Multiple ball bearings are rotatably installed on the side of the sliding block 42 closest to the first guide rod 41 and the side closest to the slide rail 4. The ball bearings abut against the first guide rod 41 and the slide rail 4, making the movement of the sliding block 42 on the first guide rod 41 and the slide rail 4 smoother.

[0047] Please refer to Figure 3 , Figure 4 and Figure 6 A curved surface is formed at the bottom end of the slide rail 4, allowing the clip to rotate 90 degrees. As the clip moves along this curved surface, it gradually rotates until it is upright. A second guide rod 51 is fixedly connected to the bottom end of the first guide rod 41, extending from the slide rail 4. The second guide rod 51 is positioned along the direction of movement of the underfloor heating pipe and is located above it. After passing the curved surface at the bottom of the slide rail 4, the clip will be upright when it reaches the second guide rod 51. Furthermore, because the second guide rod 51 is close to the underfloor heating pipe, the lower half of the clip can fit onto the pipe as it moves along it, achieving pre-installation of the pipe and clip. This facilitates subsequent installation of the clip onto the pipe below the second guide rod 51, ensuring a better installation result.

[0048] Please refer to Figure 6 and Figure 7 A sealing plate 52 is fixedly installed on the bottom surface of the main frame 1. A nail-laying opening exists between the sealing plate 52 and the second guide rod 51, allowing individual nails to fall out. A top rod 53 is slidably mounted on the sealing plate 52, abutting against the second guide rod 51. At this time, the nail-laying opening is closed by the top rod 53, allowing the nails to move along the second guide rod 51 onto the top rod 53. As the top rod 53 moves away from the second guide rod 51, the nails resting on the top rod 53 fall out of the nail-laying opening. An elastic element is provided on the sealing plate 52, controlling the movement of the top rod 53 to open and close the nail-laying opening.

[0049] An installation mechanism for installing clips onto the underfloor heating pipes is provided on the main frame 1. Specifically, the installation structure includes a separation component for separating adjacent clips, a pressing component for pressing the clips onto the pipes, and a power component for driving the separation component and the pressing component.

[0050] Please refer to Figure 6 and Figure 7 The separation assembly includes a cutting roller 61 rotatably mounted on the main frame 1 and a cutting blade 62 fixedly mounted on the cutting roller 61. The cutting roller 61 is located above the second guide rod 51. The cutting roller 61 is made of rubber and has an arc-shaped circumferential surface for better contact with the tack. The cutting blade 62 extends radially along the cutting roller 61, enabling better cutting of the connecting strip on the tack. As the cutting roller 61 rotates, it presses against the top of the tack, pushing it to the top rod 53 and against the sealing plate 52. As the cutting roller 61 continues to rotate, the cutting blade 62 presses against the connecting strip of the tack. Because the connecting strip on the tack is thin, when the cutting blade 62 rotates to a vertical position, it can squeeze between adjacent tacks, thereby cutting the connecting strip and separating the adjacent tacks.

[0051] Please refer to Figure 6 and Figure 7 The pressing assembly includes a rotating shaft 71 rotatably mounted on the main frame 1, discs 72 fixedly mounted at both ends of the rotating shaft 71, and pressing claws 73 fixedly mounted on the discs 72. When the cutting blade 62 presses against the connecting strip of the clip, the pressing claws 73 rotate to press against the sharp part of the clip. As the cutting blade 62 and the pressing claws 73 continue to rotate, adjacent clips are separated by the cutting blade 62, and the pressing claws 73 press down on the sharp part of the clip, causing the clip to fall out of the clip opening. With the continuous rotation of the disc 72, the clips are pressed firmly onto the underfloor heating pipe by the pressing claws 73, thereby installing the clips on the underfloor heating pipe.

[0052] Please refer to Figure 6 and Figure 7A cam 711 is fixedly mounted on the rotating shaft 71, and a groove 712 is formed on the circumferential surface of the cam 711. The push rod 53, under the action of an elastic element (a first spring 54), is always pressed against the circumferential surface of the cam 711. One end of the first spring 54 is fixedly connected to the sealing plate 52, and the other end is fixedly connected to the push rod 53. The first spring 54 is always in a compressed state. The end of the push rod 53 near the cam 711 is hemispherical, allowing the cam 711 to rotate more smoothly and push the push rod 53 to move. The rotation of the cam 711 causes the push rod 53 to slide synchronously on the sealing plate 52. When the push rod 53 presses against the cam 711, the nail hole is closed by the push rod 53. When the push rod 53 extends into the groove 712, the push rod 53 moves out from the nail hole. At this time, the cutting blade 62 also presses on the connecting strip of the nail, and the pressing claw 73 presses against the sharp part of the nail, causing the nail to be separated, the nail hole to open, and the nail to be pressed down, thereby realizing the transfer of the nail from the push rod 53 to the underfloor heating pipe and realizing the installation of the nail.

[0053] Please refer to Figure 2 , Figure 6 and Figure 7 The power assembly includes a first transmission gear 81 fixedly mounted on the cutting roller 61, a second transmission gear 82 fixedly mounted on the rotating shaft 71, a transmission belt 83 mounted on the first transmission gear 81 and the second transmission gear 82, and a transmission motor 84 fixedly mounted on the main frame 1. The output end of the transmission motor 84 is connected to the rotating shaft 71. A storage battery 85 is fixedly mounted on the main frame 1, and the storage battery 85, the transmission motor 84, and the drive motor 32 are electrically connected to each other, thereby supplying power to the transmission motor 84 and the drive motor 32. The switching of the transmission motor 84 and the drive motor 32 can be controlled by either a traditional switch fixed on the main frame 1 or a portable remote control switch; no restriction is placed here.

[0054] The implementation principle of this application embodiment is as follows: the underfloor heating pipe placed on the support rod 221 passes through the perforation and is then unwound under the drive of the drive roller 31, so that the underfloor heating pipe passes under the main frame 1 under the support of the support roller 11. During construction, the workers do not need to pull and unwound the underfloor heating pipe, which saves manpower and improves work efficiency.

[0055] As the underfloor heating pipe is unwound, the cutting roller 61 and the rotating shaft 71 rotate synchronously under the drive of the transmission motor 84. When the cutting blade 62 abuts against the connecting strip of the clip, the push rod 53 begins to move into the groove 712. As the cutting blade 62 separates adjacent clips, the push rod 53 extends into the groove 712, causing the clip opening to gradually open, while the pressing claw 73 abuts against the sharp part of the clip. After the clip opening is fully opened, the clip falls from the clip opening and is then pressed onto the underfloor heating pipe by the pressing claw 73, thus installing the clip onto the underfloor heating pipe.

[0056] The entire underfloor heating pipe laying process not only achieves automatic unwinding of the underfloor heating pipes but also automatic installation of clips on the pipes. The unwinding and clip installation are carried out simultaneously, resulting in a high degree of automation. This facilitates subsequent pipe laying by staff, saves manpower, and improves work efficiency.

[0057] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
